What is Otoro?
Among the other parts of tuna, the portion called “jabara” is the fattiest. Stored with ice and matured until it is tender enough. Although too long maturing process will change the color tone and texture; it gets too tender to be made into Nigiri sushi. The marbled part is very rare and expensive. Not stringy and every part is equally fatty with smooth texture.
